Hydra capture their food by paralyzing and killing the food organism by means of nematocysts, which are discharged into the prey. The prey is brought to the mouth (proctostome) by the tentacles, a response that is induced glutathione. ... The organism is then taken in through the mouth, which is star-shaped or circular.
The biomolecule described below is a _______________.
a. lipid
b. monosaccharide
c. carbohydrate
d. protein
Answer: it’s lipid
Explanation:
The biomolecule described below is a lipid because they are large and non-polluting molecules.
What is the main function of lipids?Lipids are responsible for providing energy, being in the form of fat that our body stores the excess energy we consume through food to use in times of need.
They are substances whose main characteristic is the insolubility in polar solvents and the solubility in organic solvents (nonpolar), presenting a hydrophobic nature, that is, aversion to the water molecule.
Lipids have unique characteristics that allow them to be quickly identified, for example because they are large and non-polluting molecules.

Someone can please describe to me the process a cell is living if the cell membrane is damaged
Answer:
When cells become damaged or die the body makes new cells to replace them. This process is called cell division. One cell doubles by dividing into two. Two cells become four and so on.
Explanation:
ayooo help i don’t know what this is
Look at the protein below. Which could be its function?
A.) forming muscle fiber
B.) directing the growth of cells
C.) storing energy
D.) insulating the body
Answer:
I think it's A: Forming muscle fiber
Explanation:
The function of the protein depicted in the diagram is to form a muscle fiber.
What is a muscle fiber?It is composed of myofibrils.They are contractile in nature.They are elastic in nature.They are extensible meaning they can be stretched.They are excitable meaning they have the ability to respond to a stimulusThey appear as a long thin thread and hence named.What is a muscle fiber formed of?A muscle fiber is formed of actin and myosin filaments.

What is the relationship between greenhouse and effect and sunlight ?
Answer:
In the daytime, sunlight shines into the greenhouse and warms the plants and air inside.
Explanation:
At nighttime, it's colder outside, but the greenhouse stays pretty warm inside. That's because the glass walls of the greenhouse trap the Sun's heat. The greenhouse effect works much the same way on Earth.
One explanation for why polar regions are colder than equatorial regions is that

Give three reasons why the villi in the small
intestine are perfect for absorbing food.
Answer:
Villi are specialized for absorption in the small intestine as they have a thin wall,
one cell thick, which enables a shorter diffusion path.
They have a large surface area so there will be more efficient absorption of fatty acids and glycerol into the blood stream.
The process of transferring energy during respiration occurs in a series of steps. This prevents too much heat from being released at one time. Maintaining an appropriate temperature is beneficial to an organism because A) enzymes need a proper range of temperatures to catalyze vital reactions B) cellular waste products can only be excreted in cooler temperatures C) hormones can only produce antibodies if temperatures are not excessive D) nutrients diffuse faster into cells when temperatures are lower
Answer:
A) enzymes need a proper range of temperatures to catalyze vital reactions
Explanation:
Cellular respiration is the process by which living cells synthesize ATP (energy). The synthesized energy is transferred for use in other activities. However, as stated in this question, the process of transferring energy during respiration occurs in a series of steps in order to prevent too much heat from being released at once.
The process whereby the living organism maintains an appropriate internal temperature is called HOMEOSTASIS, which is beneficial and key to an organism's survival because because enzymes need a proper range of temperatures to catalyze vital reactions. Enzymes are proteinous catalysts that gets denatured by certain factors such as high temperature, pH.

Answer:
✧･ﾟ: *✧･ﾟ:* *:･ﾟ✧*:･ﾟ✧
Hello!
✧･ﾟ: *✧･ﾟ:* *:･ﾟ✧*:･ﾟ✧
❖ A always goes with T (Adenine - Thymine)
G always goes with C (Guanine - Cytosine)
If the pairs aren't the way they're supposed to be, this can result in genetic disorders
~ ʜᴏᴘᴇ ᴛʜɪꜱ ʜᴇʟᴘꜱ! :) ♡
Answer:
The base pairing rules for DNA are governed by the complementary base pairs: adenine (A) with thymine (T) in an A-T pairing and cytosine (C) with guanine (G) in a C-G pairing. Thymine only binds with adenine in a T-A pairing and guanine only binds with cytosine in a G-C pairing.

If the volume of a gas decreases, what happens to the pressure?
If the volume of a gas increases, what happens to the pressure?
Answer:
Boyle's law. If the gas volume is decreased, the container wall area decreases and the molecule-wall collision frequency increases, both of which increase the pressure exerted by the gas (Figure 1).

The sodium-potassium pump regulates the amount of sodium and potassium inside of cells, particularly nerve and muscle cells. In this process, an ATP is burned, causing three sodium ions to be pumped out and exchanged for two potassium ions, which are pumped in by a membrane protein. Both ions go against their concentration gradients.
The sodium-potassium pump is an example of
a. phagocytosis.
b. passive transport.
c. active transport.
d. facilitated diffusion.
Answer:
Active Transport because it needs ATP

Recently in Antarctica, a penguin with all black feathers was
discovered. This trait had never been seen before. What is
the likely source for this "new" trait?
The penguin in question has a rare genetic mutation called melanism, which makes skin, fur, and feathers black due to a high concentration of the pigment melanin. It's basically the opposite of albinism, which is caused by a lack of pigment.

The energy for cellular respiration comes from the glucose that was made during photosynthesis
Answer:
True
Explanation:
Glucose and oxygen that are made with the process called photosynthesis are then used as starting products for cellular respiration. This cellular respiration later makes carbon dioxide and water are then in combination with sunlight the starting products for new photosynthesis.
